Summary
The essence of tackling age questions on the GMAT involves accurately representing mathematical relationships among ages at different times, requiring a clear definition of variables and strategic use of addition and subtraction to express age changes.
  • Age questions involve understanding relationships between ages at different times, necessitating precise variable representation.
  • A common mistake is to treat ages as fixed numbers without accounting for their change over time.
  • It's recommended to define variables as representing current ages, using addition or subtraction for past or future ages.
  • Creating equations based on these relationships allows for solving age-related problems effectively.
  • Practical example provided to illustrate the process of solving an age question by defining variables for current ages and manipulating them to express future or past ages.
